Description
Technical field
The utility model belongs to vacuum pouring precision casting production technical field, is specifically related to a kind of insulated pouring case.
Background technology
Such as, for some thin-walleds or the high temperature alloy of complexity or the precision casting of Precise Alloy, blade, hollow blade, impeller etc., usually vacuum pouring will be adopted.What domestic vacuum pouring precision casting adopted usually is at stove external heat shell, then be placed in vacuum melting furnace and carry out smelting and pouring, usual shell heating-up temperature is about 1150, but owing to must vacuumize before melting, and vacuum could melting when reaching technological requirement, pour into a mould again after melting completes, this equipment due to heating after shell from enter in stove to cast during this period of time can be very long, shell temperature declines very block, shell mould temperature is difficult to ensure, causes the precision casting yield rate of the thinner or more complicated of wall thickness can be very low or cannot complete cast.
Utility model content
The technical problem that the utility model solves: design a kind of insulated pouring case, ensure that the shell temperature of stove external heat remains stable, shell mould temperature does not reduce, and that improves precision casting waters full rate and internal soundness, in particular improves the yield rate of the precision casting of the thinner or more complicated of wall thickness.
The technical solution adopted in the utility model: a kind of insulated pouring case, described pouring box comprises thermal-insulating body, heat insulation top cover, depositing funnel and shell, described heat insulation top cover is arranged on the top of thermal-insulating body, and heat-insulating top covers and is provided with depositing funnel, described shell is arranged in thermal-insulating body, and depositing funnel is positioned at the top of shell, and the discharging opening of depositing funnel is docked with the charging aperture of shell; Described thermal-insulating body is formed by being incubated tank wall and being fixed on the heat-preservation bottom be incubated bottom tank wall, and the inner side of insulation tank wall is provided with electrothermal layer.
Resistance wire is evenly equipped with in described electrothermal layer.
Described heat insulation top cover, insulation tank wall and heat-preservation bottom are made by ceramic beaverboard.
Ceramic filter is provided with in described depositing funnel.
The utility model compared with prior art by increasing insulated pouring case in vacuum melting furnace, ensure that and put into the time period of vacuum melting furnace to casting complete from shell, shell temperature remains stable, shell mould temperature does not reduce, that improves precision casting waters full rate and internal soundness, in particular improves the yield rate of the precision casting of the thinner or more complicated of wall thickness.Adopt low-tension supply to power simultaneously, solve the technical problem of easily electric discharge in vacuum melting furnace, and structure is simple, is easy to batch production.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Detailed description of the invention
A kind of insulated pouring case, described pouring box comprises thermal-insulating body 1, heat insulation top cover 2, depositing funnel 3 and shell 4, described heat insulation top cover 2 is arranged on the top of thermal-insulating body 1, and heat insulation top cover 2 is provided with depositing funnel 3, described shell 4 is arranged in thermal-insulating body 1, and depositing funnel 3 is positioned at the top of shell 4, and the discharging opening 6 of depositing funnel 3 is docked with the charging aperture 5 of shell 4; Described thermal-insulating body 1 is made up of insulation tank wall 8 and the heat-preservation bottom 7 be fixed on bottom insulation tank wall 8, and the inner side of insulation tank wall 8 is provided with electrothermal layer 9.Be evenly equipped with resistance wire 10 in described electrothermal layer 9, and resistance wire 10 adopts LVPS to power, and realize power supply by insulated enclosure and lead to furnace chamber inside.Described heat insulation top cover 2, insulation tank wall 8 and heat-preservation bottom 7 are made by ceramic beaverboard.Ceramic filter 11 is provided with in described depositing funnel 3.
Using method of the present utility model:
1, thermal-insulating body 1 is put into vacuum melting furnace, and to connect low-tension supply be that electrothermal layer 9 is powered, then after shell 4 to be cast being heated to 1050--1150 degree by resistance-heated furnace, put into thermal-insulating body 1 and cover heat insulation top cover 2, making shell mould temperature constant to be cast between 700-1000 degree;
2, the furnace charge such as high temperature alloy or Precise Alloy is added in the crucible of vacuum melting furnace, vacuumizes, electrified regulation, fusing and refining;
3, molten metal is poured into the shell 4 be placed in thermal-insulating body 1 after completing by melting after the ceramic filter 11 be arranged in depositing funnel 3 filters;
4, after pouring metal melt is complete, the heating power supply of thermal-insulating body 1 is disconnected, when after the cool time arriving technique, thermal-insulating body 1 is taken out from vacuum melting furnace, opens top cover 2, take out shell 4, casting of metals part is taken out in shell 4, completes the processing of casting of metals part.After completing above-mentioned steps, can again pour into a mould by matched moulds next time.
